Company XYZ know that replacement times for the DVD players it produces are normally distributed with a mean of 9.4 years and a standard deviation of 1.3 years. Find the probability that a randomly selected DVD player will have a replacement time less than 7.1 years? Enter your answer accurate to 4 decimal places. P(X < 7.1 years) = If the company wants to provide a warranty so that only 3.5% of the DVD players will be replaced before the warranty expires, what is the time length of the warranty? Enter your answer in years, rounded to one decimal place warranty = years
